Abstract
A support shaft capable of supporting a wound body with a long sheet wound therearound includes a first projection located at a proximal end of an outer peripheral part, and a second projection located at a distal end of the outer peripheral part. A core body of the wound body includes a one-end-side first recess part located at one end of an inner peripheral part, an other-end-side firsts recess part located at an other end of the inner peripheral part, and a second recess part located to extend from the one end to the other end. In a state where the core body is mounted on an outer periphery of the support shaft, the first projection engages the one-end-side first recess part or the other-end-side first recess part. When the core body is mounted to the outer periphery of the support shaft, the second projection engages the second recess to allow the circumferential position of the first projection to be aligned with the circumferential position of the one-end-side first recess part or the other-end-side first recess part around a central axis.
